Hi Michel, Dereferencing is not an alternative to owl:import. Graph inclusion is a precisely defined mechanism, derefencing is not. As Berners-Lee put it in his famous (but “imperfect”) Linked Data paper, returning “useful information” when a resource URI is used as a URL is an expectation of behaviour, not a rule. And what is “useful”? In practice, dereferenceable resource URIs are a (nice!) convenience for human users. I am not aware of any large scale implementations where machines make use of dereferenceability in this sense. Linked Data Platform is an attempt to formalize this into something actionable. As far as I know, LDP never became big, although lately it has been given an important role in the SOLID-movement. Today, GraphQL is still far more popular than LDP. Best regards, -j

In the end I also had to import qudt graphs despite them being made dereferenceable by Steve. When you say: “The ontology may be dereferenced, but not individual classes.” It feels like a publication issue… But can we say that TBC needs the import to properly deal with the class-level?

In TBC however I do not see the superclass: <image002.png> <image003.png> Is that expected behaviour (ie only superclass visible when explicitly imported)?
